Why Did These Batteries Make Our List?

Motorcycle batteries differ by size, model, build type, among other factors. Your riding experience relies on the choice of the battery you make for your Harley.

The below section highlights important factors to keep in mind while selecting a battery for your Harley Davidson motorcycle.


When you think about replacing your Harley’s battery, the battery voltage is among the top considerations that come to mind. A full-sized motorcycle should have a standard battery of 12 volts. However, other small Harley bikes will operate well with as low as 6-volt batteries.

In case you’re unsure of your bike battery voltage, just look at the current battery voltage that came pre-installed by the manufacturer. 

Battery voltage is critical, and installing an incompatible battery will make some of the operating systems in your Harley function inappropriately.

Battery Lifespan

You need a battery that will serve you for several years before replacing it again. A well-maintained standard battery should run you for at least five years before replacement.

To help with an idea of how long your battery may last, you may look at the type of climate in your area and the average distance you’ll be covering with your bike.

If you take short trips and live in warmer climates, you should invest in a battery with a long lifespan. Warmer conditions make your battery discharge much faster than in cold environments. Short trips will also not give your alternator enough duration for charging the battery.

Consider plugging it in a battery tender when not using it in your Harley to extend your battery life. You may also use trickle charging as a way to preserve your battery when not in use.

Cold Cranking Amps

Cold-cranking is the ability of your battery to start the engine at the lowest temperatures. A higher CCA rating of 300 and above is the standard to start your bike engine in moderately cold climates.

To be safe, consider a CCA rating that is above the marked battery CCA; never go lower as the engine might fail to start.


Most Harley batteries are compatible with different Harley Davidson bike models when it comes to power requirements. However, that does not mean each one of them will fit well in your battery compartment.

Note down your present battery dimensions before you purchase a replacement battery. An incompatible battery may force you to design other ways to fix it on your Harley; this could damage the battery or even reduce the intended lifespan.

Engine Compatibility

Harley batteries come in different engine power sizes, although a good number are compatible.

For instance, Harley Davidson bike models like King, manufactured between 1997-2016, works well with ThrottleX HDX30L batteries.

A reliable battery will start your bike immediately when you ignite- that’s the pride of a rider. So, an investment in a high-quality battery will make your battery run as you’d expect it.

Increased Power

Apart from starting and running your motorbike, a bike battery also powers other bike accessories, making a reliable battery for your Harley essential.

Types of Batteries For Harley Davidson

Harley motorbikes will work with more than one type of battery. Below is an overview of the most common types you’ll find for your Harley today.

Absorbed Glass Mat Battery

Absorbed Glass Mat Battery (AGM) is among the lead-acid batteries available on the market today. It is a maintenance-free sealed battery that will not spill no matter the position you’ll choose to install in your Harley.

AGMs design makes the fiberglass saturate with electrolyte, then stored in a dry state instead of free liquid form. They can, therefore, resist vibration better than traditional liquid batteries.

Lithium-ion Battery

Lithium-ion batteries are a little expensive but can be a worthy investment for your Harley. With proper maintenance, these batteries will last longer than most battery types. Additionally, Lithium batteries are very light in case weight is a concern to you.


There are also rechargeable versions of Lithium-ion batteries. Unfortunately, for OEM applications, Harleys will not work with Lithium-ion batteries. However, other motorcycle companies like Ducati will work well with these batteries.

Flooded Lead-acid Battery

Flooded Lead-acid is the most ancient type of battery available on the market today. They are prone to acid spillage; hence they require handling with care. These batteries work by expelling water as the battery discharges.

The chemical reactions involved require regular refilling with water to ensure optimum operation.

Gel Batteries

These batteries are best suited for cold climates with slow and long discharges of power. They are spill-free, and you can mount them in any position. Gel batteries are also more expensive than most battery types in this list.

Top Brands in the Motorcycle Battery Space

Price Points of Batteries for a Harley Davidson

Harley batteries vary in price depending on the performance. Here is a breakdown of what to expect from batteries with these price ranges.

Under $100

Batteries in this price range are the most affordable, but you must be cautious with them. While some will perform just fine, others have despicable quality. The best advice is to stick with trusted brands with a history to deliver.

$100 to $150

These are some of the best batteries on the market you can get for your Harley. They are built from high-quality material and also have the most recent manufacture dates.

The actual battery price will depend on size, power, and brand.

$150 to $300

Most batteries in this price range are OEM (original equipment manufacturer). Materials used to manufacture these batteries are either low or high quality. Although they have recent manufacture dates, you should still check to be sure.

Do further research before picking on one of these batteries to ensure the production material used is reliable. Remember, here; you’re probably paying for the manufacturers’ motorcycle branding.

Once you know what to look out for in an ideal replacement motorcycle battery, choosing the correct battery for your bike will be a breeze.

An actionable step you can take to make sure you buy the correct battery may include noting down all the current battery features, including battery dimensions, CCA rating, voltage, and engine type. 

That way, you avoid running into incompatibility issues that may compromise bike system performance.

Check on the battery type, in case you want to upgrade, and of course, your budget range. Some of the most expensive Harley batteries are the best. However, that should not be among the top defining factors of a good Harley battery.

People Also Ask

Riders want to get the best out of their Harley batteries. Comprehensive knowledge on features, maintenance, and battery type to acquire for a Harley bike is vital. Below we answer some common questions we get from riding enthusiasts and other aspiring riders.

How Long Does a Harley Davidson Battery Last?

Unlike other machinery parts that you’d expect to wear out soon when used repeatedly, using a motorcycle battery increases its lifespan. A well-maintained motorcycle battery will go for at least five years before replacement.

Keep your battery charged and use it over and over to maximize its lifespan.

Is Higher Cranking Amps Better?

A good battery will start your engine smoothly, even in freezing climates. Higher cranking means your battery will discharge enough power to start your motorcycle engine.

How Many Volts Should a Harley Battery Have?

Harley Davidson bikes come in different sizes. They have the correct size of battery pre-installed when you first acquire them. You should be keen to check the battery’s voltage to know what replacement you’ll need when the current battery wears out.

While the standard voltage of a Harley battery is 12 volts, some small sizes of Harley bikes will run well on a 6-volt battery.

What Size is a Harley Davidson Battery?

Harley bike models are made with specific compartment dimensions to suit the correct battery sizes; hence you need to pay attention to your battery size during replacement to find the exact fit.

Harley Davidson Lithium Life Battery standard size is 150mm wide, 87mm front to back, and 146mm tall.

How Much Does a Harley Battery Weigh?

Motorcycle battery weight varies across brands and battery sizes. You’ll find OEM batteries weighing as low as eight pounds.

However, some of the flagship batteries for Harley bikes, like the Harley-Davidson Lithium Life Battery, weigh an impressive 17.6 pounds.

What Are Cold Cranking Amps?

A cold-cranking amp is a measure of your battery’s ability to start the motorcycle engine in bad weather conditions.

The amperage output is measured on a standard 12-volt battery. It is always the number of amps a battery will produce at 0°F per 30 seconds while still maintaining at least 7.2 volts per cell.  The higher your battery’s CCA rating, the better it will perform.

Are Lithium Batteries Good For Harley Davidson?

Most Lithium batteries are lighter with very high cranking amperage.  They’ll start your engine faster and smoothly than standard Harleys’ Lead-acid batteries, which makes them a better choice for your Harley Davidson motorcycle.

How Many CCA Does a Harley Need?

While many riders don’t prefer going out with their Harleys when temperatures are near freezing, leave alone zero degrees, it’s still important to know how many CCA your bike will need to start in the worst weather conditions.

Generally, Harley batteries have a slightly higher CCA rating than standard batteries. Most Harley batteries have about 300 CCA.

However, that number may vary from one bike to the other. The best CCA rating should be slightly higher than the marked CCA. Don’t go for anything below. Check on the bike manual or ask your dealer if you’re unsure.
